Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007818, here are decompositions:

5 + 1007813 = 1007818
11 + 1007807 = 1007818
17 + 1007801 = 1007818
29 + 1007789 = 1007818
47 + 1007771 = 1007818
59 + 1007759 = 1007818
89 + 1007729 = 1007818
107 + 1007711 = 1007818

Showing the first eight; more decompositions exist.
